' Specification of Letters Patent.

To allwhom it may concern: I

:Be it known that I, PETER J. LEYEN1 DECKER, a citizen of the UnitedStates, residing in Haddonfield, Camden county,

in Condensers, (being a division of my'application for patent forimprovements in condensers filed January 28, 1913, Serial No. 744,775,)of which the following. is a speci 1O fication.

My invention consists of improvements in condensers of the type forexample as-those used for refrigerating purposes where am-. monia gas isliquefied and used as a cooling.

15 agent.

The chief object of my invention is to affect a quicker condensation ofammonia and other gases than has been accomplished heretofore, and to dothe same with a less num- 2 ber of pipes.

Another object is to produce than has heretofore been produced bycondensers of the same size.

These and other objects which will be de- 25 scribed hereinafter Iattain in the following manner reference being had to the accompanyingdrawing in which, I

Figure 1, is a side elevation of a condenser constructed in accordancewith my invention; Fi 2, is an end elevation of Fig. 1 looking rom theleft; and Fig. 3, is an enlarged section of a detail of my inventionshowing a liquid-ejecting nozzle which I employ.

Referring to the drawings, Fig. 2 shows a series of three stacks ofcondensing coils 1, 2 and 3 and as all of the said stacks are of similarconstruction I will describe only one in detail. Each stack comprises aplurality of tubes 4, 5, 6,7, 8, 9, 10, 11, 12,13, 14., 15 and 16, whichare connected at their rear ends by bends 17 of any well knownconstruction. The tubes 11 and 12, and 13 and 14 are respectivelyconnected together at 45 their forward ends by bends 18 which may besimilar in construction to bends 17. Bends 19 connect the forward endsof the tubes and 6, 7 and 8, and 9 and respectively; the bend 20 whichconnects the tube 50 15 with the tube 16 being of such construction asto allow a pipe 21 connected thereto to lead to a header or liquidammonia takeoif pipe 22 which extends transversely to the stacks 1, 2and 3, or any number of stacks 55 which may be employed in thecondenser.

New- 5 Jersey, have invented certain Improvements a cooler liquid Thepipe 16 extending upwardly from the. rear end of the tube 16 and whichis shown lorokelbofi' in Fig. 1, may-be led to an equalzing chamber in amanner which is in com- ;mon practice in the art and may also beconnected to a foul gas reservoir in "any well .known manner. A pipe 23connects, the header 22 with .a liquid supply pipe or header 24 whichextends transversely to and at the base of the said stacks. The main supply inlet for the ammonia gas consists of the large header 25 whichextends transversely to the stacks '(Fig. 2) and has a series oftake-off pipes 26, 27 and 28 prefer- ;ably one for each stack of tubes.These take-0E. pipes connect respectively with the forward ends 29 ofthe bottom tubes 4 and.

supply the ammonia gas, which is under pressure, to the coils so that itcan pass or circulate through the several tubes comprising each coil orstack. Each of the pipes 26, 27 and 28 is provided with a T-joint 30which'is bored at 31 (Fig. 3) for the recep tion of a nozzle 32 havingan ejecting opening 33 of small diameter. These nozzles 32 are eachconnected by piping 34 to the liquidfsupply pipe or header 24. Thenozzles 32 are so arranged that their upper ends 35 extend and open intothe interior of the pipes 26, 27, and 28 respectively and are in freecommunication therewith. pipes 26, 27 and 28- is connected to certainEach of the v Patented Sept. 1, 1914.- 1913, Serial No. 744,775. Dividedand this. application filed August 18, 1918. Serial No. 785,358.

pipes of the stacks by relay pipes 36, 37 and 38 which respectively passthrough the bends 19 and are provided with nozzles 39, 40 and 41; eachhaving an ejection bore 42 of small diameter. The nozzle 39 is soarranged as to project into the interior of the pipe 10 and issurrounded by a sleeve 43 having an inner diameter greater than theouter diameter of the end of the nozzle. This sleeve is provided withports 44 which are adjacent the end of the nozzle. In like ,manner thenozzles 40 and 41 respectively are connected to deliver to the tubes 8and 6, and are each surrounded by a sleeve 43 similar to that justdescribed. Regulating valves may be placed in all or any of the severalpipes if desired. ,1

The nozzles 39, 40 and 41 and their co operating sleeves 43 as well asthe function of the tube 16 are described in detail in my applicationfor patent, Serial No. 744,775, filed January 28, 1913, of which thisapplication is a division, therefore said parts are not claimed hereinas they are claimed in my said parent application.

The following is a description of the operation of such parts of myinvention as rev late'to the feature of injecting liquid ammonia intothe condenser coil through the nozzles 32. Water is allowed to trickleor run over the tubes of the condenser-from the top to the bottom from asuitable source such shown by the arrows in Figs. 1 and 2. At

the same time a certain amount" of the. previously condensed or liquidammonia, which passes from the pipe 21 of each coil into the eader 22and down through the pipe 23 to the header 24, passes through thenozzles 32 and is injected in spray form into the interior-of therespective pipes 26, 27 and 28,

containing the ammonia gas. The movement of the gas passing through thesaid latter pipes carries the said liquid ammonia through the tubes ofthe coil in a precipitated form and forms a mixture of ammonia gas andliquid ammonia. Thus, the ammonia gas from the time it first enters thecondenser coils has liquid ammonia mixed therewith in a precipitatedformal. e.,s'mal1globules or particles of liquid ammonia are suspendedwithin the ammonia gas. This mix ture of ammonia as and liquid passesthrough the coils and as the liquid ammonia is a better conductorof'heat than the am monia gas it will tend to quickly relieve the gas ofits heat and convey it to the pipes where it will be taken up by thecold water flowing thereover. Therefore since ammonia gas under pressureliquefies when cooled it is obvious that by forcing a spray of .liquidammonia into contact with the gas as the latter enters the tubes ofthecondenser densation t ereof is ex edited.

WVhile I have descri (1 my invent-ion as being employed in thetreatmentof ammonia; gas the same may be advantageously used to condense otherases such, for exam- 5 0.-,ple, as carbon dioxid CO in each case aportion ofthe condensed liquid being passed .portion of the coil. g
